Thom and H. Whitney. These sheaves, generalizing the local systems that are so ubiquitous in mathematics, have powerful applications to the topology of such singular spaces (mainly algebraic and analytic complex varieties).\u003c\/p\u003e\n                                \n                \n                \u003cp\u003eThis introduction to the subject can be regarded as a textbook on modern algebraic topology, treating the cohomology of spaces with sheaf (as opposed to constant)coefficients.\u003c\/p\u003e\n                                \n                \n                \u003cp\u003eThe first 5 chapters introduce derived categories, direct and inverse images of sheaf complexes, Verdier duality, constructible and perverse sheaves, vanishing and characteristic cycles. They also discuss relations to D-modules and intersection cohomology. Later chapters apply this powerful tool to the study of the topology of singularities, polynomial functions and hyperplane arrangements.\u003c\/p\u003e\n                                \n                \n                \u003cp\u003eSome fundamental results, for which excellent sources exist, are not proved but just stated and illustrated by examples and corollaries. In this way, the reader is guided rather quickly from the basic theory to current research questions, supported in this by examples and exercises.\u003c\/p\u003e\n                            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540206651\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540206651","offer_id":39424962887773,"sku":"9783540206651","price":69.54,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6a9fdff6-c895-4c9c-bdd3-edfcc18317b5.jpg?v=1772084896","url":"https:\/\/shop.autorenwelt.de\/products\/sheaves-in-topology-von-alexandru-dimca","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
